4 Emergence of postural patterns as a function of vision and translation frequency.http://www.ncbi.nlm.nih.gov/pubmed/10322069J Neurophysiol. 1999 May;81(5):2325-39.Our results suggest that visual information was important to maintaining a fixed position of the head and trunk in space, whereas proprioceptive information was sufficient to produce stable coordinative patterns between the support surface and legs. *The CNS organizes postural patterns in this balance task as a function of available sensory information, biomechanical constraints, and translation frequency.
